I have just returned from this Camino and was greatly impressed by the work done to improve the signing. It is a revolution! There are yellow arrows everywhere, and signposts at major intersections tell the pilgrim how far it is to the next destination, and if other trails from other hiking networks link to that point.
In Catalonia, the signing is confusing into Cervera (keep to the left and follow the hydro-electric lines into the town). In Aragon, the weakest point -- from Loarre to Sarsamarcuello-- is likely due to construction. As well, on the first day, follow the detailled instructions from the Barcelona group's guide, which instruct us to ignore the yellow arrows out of Montserrat-- my guess is that they lead one to the Ignatian trail to Manresa, but I could not find anyone to confirm it. However, I went well astray in 2007 following those arrows, so I strongly recommend that would-be pilgrims get this guide-- I found it most reliable, although it takes the southern trail to Lleida, rather than the northern one to Huesca.
There are new albergues in Bolea (key available at Casa Rufino bar) and Berbegal, and the Ayuntamiento staff in Tamareite told me that they have worked hard to keep the albergue there clean and ready for pilgrims. However, it is still not clear if there is any accommodation at all between Berbegal and Huesca, and much searching brought me no information--- accordingly, I bussed that stretch, as the 35km of one of the stages would have been too much in that heat without any assurance of somewhere to sleep.
It is still solitary-- in two weeks I saw no other pilgrims, and there are considerable stretches without obvious access to water. It would likely be available at farmhouses, but they can be far apart, as much of the land is covered by very sizeable orchards. However, the welcome was warm and receptive to pilgrims. Much work has gone into improving it and both volunteers and local auhorities should be congratulated.
